Εvaluatiοn of the biοlοgic effects of an aluminium-based galvanic anοde on marine organisms
The installation of offshore structures (e.g., wind farms, ship hulls and propellers, port infrastructures.) involves the use of corrosion protection systems. Among them, galvanic anode cathodic protection (GACP) using plates made of a metal alloy, often aluminium and zinc, is one of the most practi...

The installation of offshore structures (e.g., wind farms, ship hulls and propellers, port infrastructures.) involves the use of corrosion protection systems. Among them, galvanic anode cathodic protection (GACP) using plates made of a metal alloy, often aluminium and zinc, is one of the most practiced methods. The oxidation of the anode induces a release of metal ions or oxyhydroxides into the marine environment, leading to a potential enrichment of aluminium and zinc concentrations in the water column and in the sediment near the galvanic anodes. The objective of this thesis work was to study the effects of dissolution of an aluminium-based galvanic anode on marine organisms of different taxonomic groups and trophic levels. Experiments under controlled conditions were conducted on 9 species including the Pacific oyster, Crassostrea gigas, the European abalone, Haliotis tuberculata, 4 species of microalgae, 3 species of macroalgae as well as on the microphytobenthos.
